A feed rate of 200gpm of a hydrocarbon mixture at 70C is being pumped from tank at 1 atm abs pressure to a distillation tower. the density of the feed is 46.8 lbm/ft^3. and its vapor pressure is 8.45 Psia. The velocity in the inlet line to the pump is 3 ft/s and the friction loss between the tank and pump is 3.5 ft of fluid. the net positive suction head required is 6ft.

a) how far below the liquid level in the tank must the pump be to obtain this required ( NPSH)r?

b) if the feed is at boiling point, calculate the pump position.
